Ok. Your page shills for a novelist whose first line defines "serious scholars" as being "non-Greek". No bias there on his part or yours for touting him, is there?
The article you are referring to is nothing but a brief summary of Albania's mainstream history. The author, Sam Vaknin, is not a biased person, you can check that if you want, plenty of articles by him online.
His non-Greek comment, refers to the fact that the histories of Balkans peoples are seldom accepted by their neighbors. Take Macedonia for example, they say that they are descendants of the ancient Macedonians, the Greeks say that the ancinent Macedonians were Hellenistic and the Macedonians are largely Bulgarians and slavicized Greeks. As far as Albania's hisory, the mainstream version is not accepted by certain other Balkan nations.
Synopsis: I am not anti-Greek, you made an understandable but wrong assumption.
